Program to find simple interest

What is ‘Simple Interest’?
Simple interest is a quick method of calculating the interest charge on a loan. Simple interest is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments. 
Simple Interest formula:

Simple interest formula is given by: 
Simple Interest = (P x T x R)/100 
Where, 
P is the principle amount 
T is the time and 
R is the rate

Examples :

EXAMPLE1:
Input : P = 10000
        R = 5
        T = 5
Output :2500
We need to find simple interest on 
Rs. 10,000 at the rate of 5% for 5 
units of time.

EXAMPLE2:
Input : P = 3000
        R = 7
        T = 1
Output :210

The formula to calculate the simple interest is: simple_interest = (P * T * R) / 100 where P is the principal amount, T is time & R is the rate of interest. 

C++

// CPP program to find simple interest for
// given principal amount, time and rate of
// interest.
#include<iostream>
using namespace std;
int main()
{
    // We can change values here for
    // different inputs
    float P = 1, R = 1, T = 1;

    /* Calculate simple interest */
    float SI = (P * T * R) / 100;

    /* Print the resultant value of SI */
    cout << "Simple Interest = " << SI;

    return 0;
}

C

#include <stdio.h>

int main()
{
    // We can change values here for
    // different inputs
    float P = 1, R = 1, T = 1;

    /* Calculate simple interest */
    float SI = (P * T * R) / 100;

    printf("Simple Interest = %f\n", SI);

    return 0;
}
